polyphenylene

pol-ee-FEN-uh-leen

Definition

A type of high-performance polymer characterized by its heat resistance and chemical stability, used here as part of the material polyphenylene sulfide (PPS).

Etymology

Derived from 'poly-' (many) and 'phenylene' (a chemical group derived from benzene), this term describes a polymer chain consisting of many linked phenylene units.

In the news

The article identifies polyphenylene sulfide (PPS) as the most heat-resistant thermoplastic matrix among those tested, noting its ability to retain structural strength at significantly higher temperatures than the other materials.

Tests reveal how thermoplastic composites lose strength at elevated temperatures
